FIELD

The invention relates to a climbing boot for a rail-guided climbing system, comprising a main boot body having first and second rail guide elements, wherein at least the first rail guide element, in particular the first and second rail guide elements, is/are arranged on the main boot body so as to be pivotable and/or extendable in such a way that, in the pivoted and/or extended guidance state, a climbing rail, which is arranged slidably between the first and second rail guide elements is guided by the rail guide elements by portions of the climbing rail being surrounded by the rail guide elements. The invention also relates to a rail-guided climbing system comprising this climbing boot and to a method for decoupling this climbing boot coupled to a concreting segment of a building.

BACKGROUND

It is well known that self-climbing formwork is used for the construction of tall buildings, wherein a formwork, i.e., a mold, for example for the production of concrete walls on a construction site, is moved in the climbing direction on a molded wall, which, in the case of walls, faces upward, i.e., can be clamped. In this case, rails are attached to the walls on which the formwork can be moved upwards. The rails are fastened to the wall with climbing boots. The rail can then be pushed up by these climbing boots, allowing another floor to be poured, for example using a lifting device such as a hydraulic unit. The climbing boots themselves are each fastened to the wall via a bracket.

The Rail Climbing System (RCS) from PERI, for example, uses climbing boots that serve as a connecting element between the already completed part of the building to be erected and the climbing technology and guide a vertically slidable rail on which formwork and/or protective housings are fastened.

In a climbing operation, a plurality of climbing boots arranged one below the other are generally required in order to carry and/or guide the climbing rail and to support the climbing mechanism, for example, in that the lifting device is supported on these climbing boots in order to move the rails upwards. In order to concrete a tall building, a large number of climbing boots would be required, arranged one below the other, so that the self-climbing technology can climb the entire building height. However, this is inefficient and expensive, which is why climbing boots that are no longer required, for example those that have already been “overclimbed” by the climbing system, are to be reused. This reduces the total number of climbing boots required.

The climbing boot used in the RCS system is described in DE 10 2005 030 333 B4. It essentially consists of two parts, the wall/ceiling boot and the sliding boot. The wall boot is attached to a wall or the ceiling boot on a ceiling, for example concreted. The sliding boot, which is rotatably connected to the wall/ceiling boot, is connected to the climbing rail, i.e., it serves as a guide for the climbing rail, as a support for the lifting device and as a holding point for the climbing rail. The wall/ceiling boot is removed and reinstalled in a higher position for reuse. To release the sliding boot from the wall/ceiling boot and reattach it to the new deployment location, the following steps must be performed (steps 1 to 6: releasing and transporting the climbing boot, steps 7-10: fastening the climbing boot):

-   -   1. The climbing boot 10 must be “folded open,” i.e., in the         event that the two claws 50 are designed to be foldable, both         claws 50, which surround the climbing rail 20, must be opened.         For this purpose, two plug-in pins 56 have to be pulled out and         then be reinserted into the sliding boot 16,     -   2. loosening the cotter pin on the fastening bolts 34,     -   3) pulling out the fastening bolts 34, wherein the climbing boot         must be held, optionally by a second person,     -   4) the climbing boot 10 can then be lifted out between the wall         14 and the climbing rail 20,     -   5) disassembling the wall/ceiling boot 18,     -   6) both parts, the wall/ceiling boot 18 and sliding boot 16,         must finally be transported upwards to the new climbing region,         i.e., the region in the climbing direction in which the climbing         boot is to be used,     -   7) mounting the wall/ceiling boot 18 at the anchor point in the         new climbing region that is designated for this purpose,     -   8) an opened gliding boot 16 in which the claws 50 are open must         be positioned and held in relation to the wall/ceiling boot 18         in such a way that the fastening bolt 34 reconnects the sliding         boot 16 to the wall/ceiling boot 18,     -   9) securing the cotter pin to fastening bolts 34, and     -   10) the sliding boot 16 must be “folded closed” so as to create         a guide for the climbing rail 20, i.e., the two claws 50, which         are still open, must be closed. For this purpose, the two         plug-in pins 56 have to be pulled out, the claws 50 closed and         the plug-in pins 56 inserted again.

According to another document EP 3 241 959 A1, a climbing boot is disclosed in which a recess 16 is present in each of two claws 11 of the climbing boot (see FIG. 7 of this document). By manually engaging the recesses 16, the claws 11 can be individually pulled “backwards” and thus the climbing boot can be opened. The working steps for releasing, transporting and fastening substantially correspond to those necessary in EP 3 241 959 B1.

The known climbing boots have the following disadvantages when releasing from and fastening to a wall or ceiling:

-   -   a plurality of handles are necessary, resulting in poor         ergonomics and a high susceptibility to errors in the design of         the handles,     -   a plurality of connecting elements, for example wall/ceiling         boots and sliding boots, are required, i.e., the risk of losing         these connecting elements,     -   a plurality of steps must be carried out at the same time, for         example the climbing boot must be held at a hole position,         wherein the climbing boot must be designed to be heavy in         relation to its load and can be held by a worker only briefly in         order to insert a fastening bolt into the hole of the hole         position, which fastening bolt is held in the other hand, which         is ergonomically disadvantageous and error-prone, and     -   even two people are optionally required to release and re-fasten         the climbing boot, for example if the climbing boot can only be         held with two hands and the fastening bolt must be inserted into         the hole of the hole position by another worker.

SUMMARY

In contrast, the object of the present invention is to provide a compact and portable climbing boot for a rail-guided climbing system that can be decoupled easily and without great manual effort from a wall or ceiling of a concreting segment of a building and can be released from being guided by a climbing rail of the climbing system. In particular, the climbing boot is intended to allow the rail-guided climbing system to be decoupled quickly and ergonomically from the wall or ceiling of the concreting segment and to be released from being guided by the climbing rail without the possibility of losing parts of the climbing boot. Thus, with the climbing boot according to the invention, the disadvantages of the prior art when decoupling the climbing boot from the wall or ceiling and releasing the climbing boot from being guided by the climbing rail are to be avoided or at least reduced, which avoids errors when releasing the climbing boot from the wall or ceiling and from being guided by the climbing rail and increases the working safety.

This problem is solved by a climbing boot and a method for decoupling a climbing boot fastened to a concreting segment of a building.

The object according to the invention is thus achieved by a climbing boot for a rail-guided climbing system, which can be used in particular as a climbing formwork, climbing frame, protective climbing wall and/or climbing working platform. The climbing boot comprises a main boot body having first and second rail guide elements, wherein at least the first rail guide element, in particular the first and second rail guide elements, is/are arranged on the main boot body so as to be pivotable and/or extendable in such a way that, in the pivoted and/or extended guidance state, i.e., in the “closed” position, a climbing rail, which is arranged slidably between the first and second rail guide elements is guided by the rail guide elements by portions of the climbing rail being surrounded by the rail guide elements. The climbing boot further comprises a receiving element that is arranged on the main boot body and is designed to interact with a first portion of a bracket element, arranged in a stationary manner on a concreting segment of a building, in such a way that, when the receiving element is attached to the first portion of the bracket element, a load of the climbing boot can be introduced into the bracket element. Finally, the climbing boot comprises a sliding element that is provided with a handle and is designed in such a way that it is mechanically coupled to the main boot body and the first rail guide element, and, when the first rail guide element is in the guidance state, sliding of the sliding element in relation to the main boot body in a decoupling direction, which sliding is caused by an actuation of the handle, results in the first rail guide element being set into the non-pivoted and/or retracted initial state, i.e., set into the “open” position, in order to release the climbing boot from being guided by the climbing rail.

The main boot body and the sliding element can each be designed as a frame, wherein they can be formed as a flat body with or without recesses. The main boot body and the sliding element can consist of one or more parts/components that are detachably, i.e., reversibly, or irreversibly, connected to one another. The parts or components of the main boot body and sliding element can each be manufactured from different materials, for example steel, aluminum or carbon fiber composite materials, or a combination thereof, in order to keep the weight of the main boot body, and thus the weight of the climbing boot, low. The advantages according to the invention are already obtained when the sliding element provided with the handle is mechanically coupled only to the main boot body and the first rail guide element. However, in a preferred embodiment, in addition to the main boot body, the sliding element is mechanically coupled to both the first rail guide element and also to a locking element that serves to lock the climbing boot on the bracket element. In the following, a coupling is already understood as a contact of one element with another element for the introduction or removal of forces. Fastening is understood to mean a connection, for example a screw or welded connection, between two elements in which the elements are fixedly connected to one another in a form-fitting and/or force-fitting manner, i.e., not displaceable relative to one another.

On the main boot body, the first and/or second rail guide elements can be arranged so as to be pivotable and/or extendable by means of mechanical coupling members, for example in the form of an axle element, such as a cylindrical bolt, and/or a sliding element. A combination of pivotable and extendable arrangement of the at least one rail guide element on the main boot body is possible. Preferably, both the first and the second rail guide elements are attached to the main boot body so as to be pivotable and can be transferred to the pivoted-out guidance state by pivoting from the pivoted-in initial state, and vice versa.

The receiving element arranged on the main boot body can be arranged on the main boot body by means of mechanical coupling members, for example in the form of a screw or a bolt, or in one piece with the main boot body. The receiving element, in the form of a hook open counter to a climbing direction, is preferably arranged on an outer portion of the main boot body, for example on a lower portion of the main boot body, when the climbing boot is aligned with its longitudinal axis in the vertical climbing direction. In this case, the handle of the sliding element is preferably arranged in an upper portion of the sliding element. Any shape of the mechanical coupling is possible by applying the receiving element to the first portion, provided that it allows the load applied to the climbing boot, which load can be formed by the own weight of the climbing boot or a load of the climbing system or a part thereof applied to the climbing boot, to be introduced into the first portion of the bracket element. For example, it may be sufficient to place the receiving element on the first portion of the bracket element to avoid movement of the receiving element in the direction of gravity. The mechanical coupling between the receiving element and the bracket element can be eliminated by separating these elements from one another. The receiving element can be attached to the main boot body so as to be pivotable and can be transferred to the pivoted-out receiving state by pivoting from the pivoted-in initial state, and vice versa, wherein a locking function of the receiving element on the bracket element is not necessary. The receiving element can interact with the locking element of the main boot body to lock the climbing boot on the bracket element when the locking element is in the locked state. When the climbing boot is aligned with its longitudinal axis in the vertical climbing direction, the receiving element can have a substantially horizontally aligned and cylindrical recess that is open downwards counter to the climbing direction to receive a bracket support element, for example in the form of a cylindrical bolt, as a portion of the bracket element when the climbing boot is placed on the bracket element from above, i.e., in the direction opposite to the climbing direction, or is suspended in the bracket element. The bracket element can be designed as a suspension element for suspending the climbing boot, for example as a hook-in ring, wherein all the embodiments of the first portion of the bracket element are comprised that interact with the receiving element in such a way that, when the receiving element is attached to the first portion of the bracket element, a load of the climbing boot can be introduced into the bracket element.

The sliding element and the main boot body can be arranged so as to be slidable substantially parallel to one another in the decoupling direction. The handle is preferably arranged in an outer portion of the sliding element and is connected to the sliding element detachably, for example by means of a screw or latching/snap connection, or irreversibly, for example in the case of an integral formation.

The sliding element can be coupled to the main boot body, the first rail guide element and the locking element by means of mechanical coupling members, for example in the form of an axle element, such as a cylindrical bolt, and/or a sliding element, for example in the form of a slide, which can be guided over recesses in the main boot body, or the sliding element itself, and/or lever element and/or an entraining element, for example in the form of a rod, so as to be pivotable and/or extendable. A combination of a pivotable and extendable arrangement of the sliding element on the first and/or second rail guide element and the locking element is possible. Thus, when the climbing boot is coupled to the bracket element and is oriented with its longitudinal axis in the vertical climbing direction, the sliding element can be arranged so as to be substantially vertical and parallel to the main boot body, and can be coupled via two substantially vertically oriented rods to ends of an axle element designed as a bolt for pivoting the locking element in the form of a latching lug in and out. Furthermore, in this case, the sliding element can be rotatably connected to the vertically pivotable first and second rail guide elements by means of two entraining elements designed as arms in such a way that, when the handle is actuated upwards in the vertical climbing direction, both the locking element and the first and second rail guide elements are set into the initial state and thus the climbing boot is decoupled from the bracket element and released from being guided by the climbing rail.

Alternatively, the sliding element can be mechanically coupled to the main boot body, the first and optionally the second rail guide element and the locking element by means of pipe screw contours, also referred to as slides. In this embodiment, the handle is connected to a rail or integrated into the rail, wherein, in the mounted state of the climbing boot, the rail can only be slid/moved relative to the main boot body in and against the climbing direction, for example vertically. The rail can be designed as part of the sliding element. When the handle is moved in the climbing direction, the rail moves in the climbing direction, for example vertically upwards, and when the handle is moved counter to the climbing direction, the rail moves against the climbing direction, for example vertically downwards. Parallel to the rail, a further rail portion, the length of which can be shorter than the length of the rail in its longitudinal direction, such as the rail on one end of the rail in the climbing direction, for example an upper end of the rail, can be connected to the rail or integrated into the rail and can thus be connected to the handle in such a way that a free end of the rail portion, in the case of a closed climbing boot, can engage both in a first recess of the main boot body and in a first recess of the first or second rail guide element in order to secure the position of the rail guide element. The other, for example lower end of the rail, which, like the free end of the rail portion, can engage in a second recess of the main boot body and also in a second recess of the first or second rail guide element, can also serve to secure the position of the rail guide element.

A rod-shaped element, for example a bolt, can be fixed to the rail perpendicular to a longitudinal axis of the rail or can be integrated into rail, which rod-shaped element moves along with the rail when the handle is moved in or against the climbing direction, for example vertically upwards and downwards. The rod-shaped element can be guided by a rod-shaped guide element, for example a further rail or a cylinder or axle element arranged parallel to the rail. The first rail guide element or the first and second rail guide elements has a third curved recess having a width that allows a free end and/or a portion of the rod-shaped element to engage in the recess or guide the recess, i.e., allows it to run in the recess. The curved recess can have a helical or threaded profile in order to rotate the rail guide element when the rod-shaped element running in the recess is displaced in or counter to the climbing direction relative to the main boot body by an actuation of the handle. If, when the climbing boot is closed, the handle for unlocking the climbing boot is actuated/pulled in the climbing direction, for example upwards, the rail moves with the rod-shaped element in the climbing direction, i.e., for example vertically upwards, when the main boot body is stationary. Because the rail and the rod-shaped element can only be displaced in the climbing direction, for example vertically upwards, the rod-shaped element guides the rail guide element during the displacement of the rod-shaped element in such a way that, due to the curved recess, the rail guide element also rotates to such an extent that a fictitious straight line of the recess is formed at the location of the rod-shaped element over the displacement of the rod-shaped element in the climbing direction, along which the rod-shaped element can move.

The first and/or second rail guide element can each comprise an at least in part cylindrical hollow body, into which the third curved recess is introduced, for example over a length of the displacement path of the handle relative to the main boot body. The rail can thus be guided in the at least in part cylindrical hollow body in such a way that the rod-shaped element can engage in the recess along its displacement path in order to guide the first and/or second rail guide element in such a way that it is rotated relative to the main boot body during the displacement of the handle. If the first and/or second rail guide elements are to be rotated in relation to the main boot body to close the climbing boot, the handle is displaced in relation to the main boot body counter to the climbing direction in the same way as when the climbing boot is opened, such that, because the rail and the rod-shaped element can only be displaced counter to the climbing direction, for example vertically downwards, the rod-shaped element guides the respective rail guide element during the displacement of the rod-shaped element in such a way that the respective rail guide element rotates with the curved recess in order to close the climbing boot.

The climbing boot according to the invention for the field of construction engineering therefore has a handle on the sliding element, with the actuation of which the climbing boot can be easily separated from the bracket element and released from being guided by a climbing rail when the sliding element is slid in the decoupling direction in relation to the main boot body, which sliding is caused by the actuation of the handle. Preferably, the climbing boot can be recoupled to the bracket element at the handle when the sliding element is slid in the coupling direction in relation to the main boot body counter to the decoupling direction, which sliding is caused by the actuation of the handle. By actuating the handle, for example by means of a pulling movement, i.e., “pulling,” the rail guide elements, which engage around the climbing rail for guidance, open. Optionally, actuating the handle also opens a locking element, by means of which the climbing boot is locked on the bracket element, and/or a latching/snap element in the form of a pawl, into which the climbing rail is suspended before opening. This allows the climbing boot to be quickly and easily decoupled/released from the bracket and subsequently removed with only one handle. A plurality of functions are performed within the climbing boot by the actuated handle on the sliding element of the climbing boot. This is necessary in order to easily decouple/release and remove, i.e., remove or fasten, the climbing boot between the bracket element of a wall or ceiling and the climbing rail. When actuating, for example “pulling” the handle, the rail guide elements are unlocked and opened, the receiving element is separated from the bracket element and an existing locking element and/or latching/snap element is in each case set into the initial state, i.e., opened or unlocked. Now it is easy to release and remove the climbing boot, i.e. to remove the climbing boot between the climbing rail and the building.

If the climbing boot is subsequently reattached at a different location of the building to be constructed, the rail guide elements and the optional locking element and/or optional latching/snap element are closed to suspend the climbing rail by a further actuation of the handle in the coupling direction, for example by a downwards pulling movement or a pushing movement, i.e., “pushing” in the reverse order. The climbing boot according to the invention thus is able to be released from a wall or ceiling and from being guided by a climbing rail of the climbing system easily and without a great deal of manual effort with only one handle. Because the climbing boot can be held by the handle, which also releases the climbing boot from the bracket element and from being guided by a climbing rail when it is actuated, it allows the climbing boot to be released quickly and ergonomically from the wall or ceiling of the concreting segment and be released from being guided by the climbing rail. Because the sliding element is mechanically coupled to the main boot body and the first rail guide element and thus movable parts of the climbing boot are mechanically coupled, these parts of the climbing boot cannot be lost when the climbing boot is released.

As mentioned above, the climbing boot can comprise a locking element that is arranged so as to be pivotable and/or extendable on the main boot body and is designed to interact with the first portion of the bracket element and the receiving element or with a second portion of the bracket element in such a way that, in the pivoted and/or extended locking state, the climbing boot is releasably locked to the bracket element, wherein the sliding element provided with the handle is designed in such a way that it is mechanically coupled to the main boot body, the first rail guide element and the locking element, and, when the first rail guide element is in the guidance state and the locking element is in the locking state, sliding of the sliding element in relation to the main boot body in a decoupling direction, which sliding is caused by an actuation of the handle, results in the first rail guide element and the locking element being set in each case into the non-pivoted and/or retracted initial state in order to release the climbing boot from being guided by the climbing rail and to release it from being locked on the bracket element.

The locking element that is arranged so as to be pivotable and/or extendable on the main boot body can be arranged on the main boot body by means of mechanical coupling members, for example in the form of an axle element, such as a cylindrical bolt, or a sliding element, so as to be pivotable and/or extendable. A combination of pivotable and extendable arrangement of the at least one locking element on the main boot body is possible. The locking element is preferably arranged as a latching/snap element in the form of a nose on an outer portion of the main boot body, for example on a lower portion of the main boot body, when the climbing boot is aligned with its longitudinal axis in the vertical climbing direction. In this case, the handle of the sliding element is preferably arranged in an upper portion of the sliding element. The locking element can be attached to the main boot body so as to be pivotable and can be transferred to the pivoted-out locking state by pivoting from the pivoted-in initial state, and vice versa. The locking element can interact with the receiving element of the main boot body to fasten the climbing boot to the bracket element when the locking element is in the locked state. When the climbing boot is aligned with its longitudinal axis in the vertical climbing direction, the receiving element can have a substantially horizontally aligned and cylindrical recess that is open downwards counter to the climbing direction to receive a bracket support element, for example in the form of a cylindrical bolt, as a first portion of the bracket element when the climbing boot is placed on the bracket element from above, i.e., in the direction opposite to the climbing direction.

As already mentioned, the climbing boot can further comprise at least one latching/snap element that is arranged on the main boot body so as to be pivotable and/or extendable and is designed to interact with a holding element of the climbing rail and/or a climbing lift rail, which can be displaced relative to the climbing rail and is guided by the climbing rail, for holding the at least one latch/snap element in such a way that, in the pivoted and/or extended holding state, i.e., in the “closed” position, the climbing rail and/or climbing lift rail can be suspended in the climbing boot in the opposite direction to a climbing direction, wherein the sliding element is designed in such a way that it is mechanically coupled to the main boot body, either the first rail guide element or the first rail guide element and the locking element, and additionally to the latching/snap element. If either the first rail guide element in the guidance state or the first rail guide element and the locking element are in the locked state, and additionally the latching/snap element is in the pivoted and/or extended holding state, i.e., in each case in the “closed” position, sliding of the sliding element in relation to the boot main body, which sliding is caused by the actuation of the handle, results in either the first rail guide element or the first rail guide element and the locking element, and additionally the latching/snap element, being set in each case into the non-pivoted and/or retracted initial state, i.e., in each case to the “open” position, in order to release the climbing boot either from being guided by the climbing rail or to release it from being guided by the climbing rail and from being locked on the climbing rail, and additionally to free it from being held by the climbing rail and/or climbing lift rail. In this embodiment, the latching/snap element complements the function of the handle so that, when the handle is actuated, not only is the climbing boot separated from the bracket element and is released from being guided by the climbing rail, but it is also freed from the holding state of the climbing rail/climbing lift rail.

The latching/snap element can comprise either one pawl arranged substantially on a longitudinal axis of the climbing boot or two pawls arranged substantially horizontally spaced apart from the longitudinal axis, in particular at substantially equal distances from the longitudinal axis. In this case, the pawl or the two pawls are designed to interact with one or more holding elements of the climbing rail for holding the pawl or the two pawls of the first latching/snap element in such a way that, in the pivoted and/or extended holding state, the climbing rail can be suspended in the climbing boot in the opposite direction to a climbing direction. Two pawls can carry a higher load than only one pawl, wherein the pawls can be actuated in pairs and can also be mechanically connected to one another in pairs.

The climbing direction can indicate a direction upwards, i.e., an upward direction, wherein a sideways direction is also possible, for example in tunnel construction. Oblique linear translational or curved directions, for example rotational directions, are also possible as a climbing direction. The latching/snap element that is arranged so as to be pivotable and/or extendable on the main boot body can be arranged on the boot base body by means of mechanical coupling members, for example in the form of an axle element, such as a cylindrical bolt, or a displacement element, so as to be pivotable and/or extendable. A combination of pivotable and extendable arrangement of the at least one latching/snap element on the main boot body is possible. The climbing direction can correspond to the decoupling direction. Other directions relative to one another, for example opposite or at right angles to one another, are also possible, however.

In a particularly preferred embodiment, the sliding element is designed in such a way that, if the first rail guide element, the first rail guide element and the locking element, the first rail guide element and the latching/snap element, or the first rail guide element, the locking element and the latching/snap element are in each case in the non-pivoted and/or retracted initial state, i.e., in the “open” position, sliding of the sliding element in relation to the main boot body in a coupling direction opposite to the decoupling direction, which sliding is caused by an actuation of the handle, results in the first rail guide element being set into the guidance state, the first rail guide element being set into the guidance state and the locking element being set into the locking state, the first rail guide element being set into the guidance state and the latching/snap element being set into the holding state, or the first rail guide element being set into the guidance state, the locking element being set into the locking state and the latching/snap element being set into the holding state, i.e., in the “closed” state, in order to move the climbing boot into the guide of the climbing rail, to move the climbing boot into the guide of the climbing rail and lock it on the bracket element, to move the climbing boot into the guide of the climbing rail and set it into the holding state of the climbing rail and/or climbing lift rail, or to move the climbing boot into the guide of the climbing rail, lock it on the bracket element and set it into the holding state of the climbing rail and/or climbing lift rail. The sliding element is therefore designed such that, when the handle is actuated, the resulting sliding of the sliding element takes place in relation to the main boot body in a coupling direction opposite to the decoupling direction, the climbing boot is coupled to the bracket element and is moved so as to be guided by the climbing rail and, optionally, the climbing boot is additionally locked on the bracket element and/or is set into the holding state of the climbing rail/climbing lift rail. The handle can thus be used both to decouple and/or couple the climbing boot to the bracket element and/or the climbing rail.

If the climbing boot comprises at least one further latching/snap element that is arranged on the main boot body so as to be pivotable and/or extendable and interacts with at least one further holding element of the climbing rail and/or the climbing lift rail for holding the further latching/snap element in such a way that, in the pivoted and/or extended holding state, the climbing rail and/or the climbing lift rail can be suspended in the climbing boot in the direction opposite the climbing direction, wherein the latching/snap elements can be actuated simultaneously or independently of one another by the handle, the sliding plate can be designed in such a way that, after the handle has been actuated, the climbing boot can be released not only from the climbing rail but separately or additionally from the climbing lift rail. The use of the climbing boot in climbing systems having a plurality of pawls for holding the climbing lift rail is also possible in this way.

It is preferred if the climbing boot is coupled to the bracket element and a longitudinal axis of the climbing boot is oriented in the climbing direction, a first latching/snap element of the latching/snap elements is arranged on the longitudinal axis of the climbing boot in the climbing direction and second and third latching/snap elements of the latching/snap elements are arranged so as to be spaced substantially vertically from the longitudinal axis, in particular at equal distances. If the climbing direction points vertically upwards, the second and third latching/snap elements are arranged substantially horizontally spaced apart from the longitudinal axis. In this way, the climbing boot can transfer a load from the climbing rail to the wall or the ceiling that greater than a load that is received by only one or two latching/snap elements when the climbing rail and/or climbing lift rail is suspended. The symmetrical alignment of the latching/snap elements with respect to the longitudinal axis simplifies the structure of the climbing boot. In addition, the load of the climbing boot is optimized when the latching/snap elements are aligned symmetrically with respect to the longitudinal axis.

It is advantageous if the first latching/snap element is arranged relative to the main boot body in such a way that it interacts with the further holding element of the climbing lift rail for latching/snapping the first latching/snap element, and the second and third latching/snap elements are arranged relative to the main boot body in such a way that, for latching/snapping the second and third latching/snap elements, they interact either with further holding elements of the climbing lift rail or with further holding elements of the climbing rail, which are in each case different from the further holding element of the climbing lift rail for latching/snapping the first latching/snap element. In this embodiment, the second and third latching/snap elements can be used for holding elements in the climbing rail or for further holding elements in the climbing lift rail, which leads to a high flexibility in the use of the climbing boot on the construction site.

It is also advantageous if first and second pawls of the first latching/snap elements are arranged substantially on a first axis substantially perpendicular to the longitudinal axis of the climbing boot at a distance from the longitudinal axis, in particular at substantially equal distances from the longitudinal axis, and second and third further latching/snap elements are arranged at a distance therefrom in or opposite the climbing direction or at the same level in the climbing direction on a second axis substantially perpendicular to the longitudinal axis at a distance from the longitudinal axis, in particular at substantially equal distances from the longitudinal axis. Due to the distribution of the load on two pawls of the first latching/snap element and in each case one pawl of the second and third further latching/snap element, wherein the first and second pawls of the first latching/snap element and the pawls of the second and third further latching/snap elements can be actuated in pairs, the permissible load can be higher than in an embodiment in which the first latching/snap element has only one pawl. In order to keep the design compact perpendicular to the longitudinal axis, the two pawls of the first latching/snap element can be arranged offset relative to the second and third further latching/snap elements in or counter to the climbing direction.

Depending on the design of the climbing rail and/or climbing lift rail, it can be advantageous for first distances from the longitudinal axis of the first and second pawls of the first latching/snap element to differ from second distances of the second and third further latching/snap elements from the longitudinal axis, in particular to select the first distances to be smaller than the second distances when the first and second pawls of the first latching/snap element are arranged at a distance from the second and third further latching/snap elements in or counter to the climbing direction or are located at the same height in the climbing direction with respect to the second and third further latching/snap elements. The first and second pawls of the first latching/snap element can be designed to interact with holding elements of the climbing lift rail for holding the first and second pawls of the first latching/snap element in such a way that, in the pivoted and/or extended holding state, the climbing lift rail can be suspended in the climbing boot in the opposite direction to a climbing direction, and the second and third further latching/snap elements) can be designed to interact with one or more holding elements of the climbing rail for holding the second and third further latching/snap elements in such a way that the climbing rail can be suspended in the climbing boot in the opposite direction to a climbing direction in the pivoted and/or extended holding state. The reverse embodiment in which the first and second pawls of the first latch/snap element interact with the climbing rail and the second and third further latching/snap elements interact with the climbing lift rail, is also possible.

It is particularly preferred when the climbing boot is coupled to the bracket element and a/the longitudinal axis of the climbing boot is oriented upward in a/the vertical climbing direction, the handle is arranged in an upper portion of the climbing boot or forms an upper end of the climbing boot, and the sliding element is coupled at least to the main boot body in such a way that the actuation of the handle in the decoupling direction is effected by means of a pulling movement, in particular with one hand, in the climbing direction vertically upwards and away from the main boot body. In this way, the climbing boot can be released from being coupled and optionally from being locked with the bracket element with one hand upwards and can be freed from a possible additional holding state of the climbing rail and removed from the wall or ceiling.

A particularly advantageous embodiment is provided when the climbing boot comprises a finger sliding element that is provided with a finger grip and is arranged slidably with respect to the main boot body and the sliding element, which finger sliding element is designed in such a way that it is coupled to the main boot body, the sliding element, the first rail guide element and the latching/snap element, and, if either the first rail guide element is in the guidance state or the first rail guide element is in the guidance state and the locking element is in the locking state, and the latching/snap element is in the holding state, i.e., the handle is not actuated, finger sliding of the finger sliding element with respect to the main boot body and the sliding element in an unlocking direction, which finger sliding is caused by an actuation of the finger grip, results in the first rail guide element being locked in the pivoted and/or extended guidance state and the latching/snap element being set into the non-pivoted and/or retracted initial state in order to free the climbing boot from the holding state of the climbing rail or climbing lift rail and to guide the climbing rail or climbing lift rail from the climbing boot. If a plurality of latching/snap elements are present, the finger grip can be designed in such a way that the latching/snap elements can be actuated simultaneously or independently of one another by the finger grip. By actuating the finger grip in the unlocking direction, the climbing boot can thus be released from the climbing rail or climbing lift rail without releasing the climbing boot from being locked on the bracket element and releasing the climbing rail or climbing lift rail from being guided. In this way, the climbing rail/climbing lift rail can be easily displaced by the bracket element in the climbing direction or counter to the climbing direction without decoupling/releasing the climbing boot. The climbing boot can also be released from the climbing rail/climbing lift rail before the climbing boot is released from the bracket element, which simplifies the process of releasing the climbing boot from the climbing rail/climbing lift rail.

The climbing boot is of a particularly advantageous design when the finger grip comprises a first finger grip element and a second finger grip element, wherein the first finger grip element is designed in such a way that the at least one latching/snap element can be actuated by the first finger grip element and the second finger grip element is designed in such a way that the at least one further latching/snap element can be actuated by the second finger grip element independently of the at least one latching/snap element. In this way, the climbing boot can be released/unlocked independently from the climbing rail or from the climbing lift rail.

The climbing boot is advantageously designed such that, when the finger displacement element is displaced relative to the main boot body and the sliding element is displaced about the finger displacement, i.e., the finger grip is actuated, the finger displacement element can be latched directly or indirectly to the main boot body and/or the sliding element, in particular by means of a central axle element, for example in the form of a bolt or a screw. When the finger sliding element is locked on the main boot body and/or the sliding element, the climbing rail/climbing lift rail remains released from the climbing boot when the handle is actuated for releasing the climbing boot from the bracket element, i.e., in the decoupling direction, or for fastening the climbing boot to the bracket element, i.e., in the coupling direction. This facilitates the decoupling of the climbing boot.

By pulling and locking the finger sliding element, the latching/snap element for holding the climbing rail/climbing lift rail can be set into the initial state, i.e., the “open” position. In one embodiment, the setting into the “open” position can only be done with a closed climbing boot, i.e., when the locking element is set into the locking state, i.e., in the “closed” position. Due to the coupling of the locking element and the rail guide elements by the sliding element, it is not possible to “open” the rail guide elements. In addition, the actuation of the finger grip can lock the mechanism for “opening” the rail guide elements by means of a spring element that, when the finger grip is actuated, holds the locking element in the “closed” position and, due to the coupling to the rail guide elements by means of the sliding element, also holds the at least first rail guide element in the “closed” position. When the finger grip is not actuated, the climbing boot can be in the state or the working position where the rail guide elements are in the guidance position, an existing locking element is in the locking state, and an existing latching/snap element is in the holding state.

If the handle is designed as a first web and the finger grip is designed as a second web, wherein the first and second webs are arranged so as to be substantially parallel to one another, in particular at a distance of 3 to 4 cm from one another, the finger grip can be actuated when the handle is gripped. The climbing boot can thus be gripped when the finger grip is to be actuated. This simplifies the actuation of the finger grip, prevents errors when the finger grip is actuated and therefore ensures a high level of safety when using the climbing boot.

The invention also comprises a rail-guided climbing system that comprises the climbing boot according to the invention, the bracket element arranged in a stationary manner on the concreting segment of the building and the climbing rail arranged slidably between the rail guide elements of the main boot body, in particular with a climbing lift rail that is slidable with respect to the climbing rail and guided by the climbing rail. A total length of the at least one climbing rail can be selected such that the climbing rail is guided by at least two climbing boots that are spaced apart from one another at a predetermined distance, for example a floor height.

The invention also comprises a method for decoupling a climbing boot coupled to a concreting segment of a building for a rail-guided climbing system, which can be used in particular as a climbing formwork, climbing frame, protective climbing wall and/or climbing working platform. The method comprises the following steps:

-   -   a) providing the climbing boot having a main boot body with         first and second rail guide elements, wherein at least the first         rail guide element, in particular the first and second rail         guide elements, is/are arranged on the main boot body so as to         be pivotable and/or extendable in such a way that, in the         pivoted and/or extended guidance state, a climbing rail arranged         slidably between the first and second rail guide elements is         guided by the rail guide elements in that portions of the         climbing rail are gripped by the rail guide elements,     -   b) providing a receiving element that is arranged on the main         boot body and is designed to interact with a first portion of a         bracket element, arranged in a stationary manner on the         concreting segment of the building, in such a way that, when the         receiving element is attached to the first portion of the         bracket element, a load of the climbing boot can be introduced         into the bracket element, and     -   c) providing a sliding element that is provided with a handle,         arranged slidably with respect to the main boot body and guided         by the main boot body, which sliding element is designed in such         a way that it is mechanically coupled to the main boot body and         the first rail guide element, and, when the first rail guide         element is in the guidance state, sliding of the sliding element         in relation to the main boot body in a decoupling direction,         which sliding is caused by an actuation of the handle, results         in the first rail guide element being set into the non-pivoted         and/or retracted initial state in order to release the climbing         boot from being guided by the climbing rail,     -   d) actuating the handle, wherein the generated sliding of the         sliding element in relation to the main boot body results in the         first rail guide element being set into the non-pivoted and/or         retracted initial state, and     -   e) separating the receiving element from the first portion of         the bracket element and releasing the climbing boot from being         guided by the climbing rail).

The effects and advantages of this method according to the invention for decoupling a climbing boot coupled to a concreting segment of a building correspond to those of the climbing boot according to the invention described above for a rail-guided climbing system. In the method steps, when the climbing rail is mentioned, it always means a climbing rail with or without a climbing lift rail.

A method for decoupling the climbing boot coupled to the concreting segment of the building for the rail-guided climbing system, wherein the climbing boot is arranged between the concreting segment and a climbing rail guided by the climbing boot, is realized in a preferred embodiment of the invention when

-   -   step b1) is additionally carried out between steps b) and c):         providing a locking element that is arranged so as to be         pivotable and/or extendable on the main boot body and is         designed to interact with the first portion of the bracket         element and the receiving element or a second portion of the         bracket element in such a way that the climbing boot can be         releasably locked on the bracket element in the pivoted and/or         extended locking state,     -   in step c), the sliding element is designed in such a way that         it is mechanically coupled not only to the main boot body and         the first rail guide element, but also to the locking element,         and, if not only the first rail guide element is in the guidance         state, but also the locking element is in the locking state,         sliding of the sliding element in relation to the main boot body         in the decoupling direction, which sliding is caused by an         actuation of the handle, results in not only the first rail         guide element, but also the locking element being set into the         non-pivoted and/or retracted initial state in order to release         the climbing boot from being guided by the climbing rail and to         release it from being locked on the bracket element.     -   in step d), the sliding of the sliding element in relation to         the main boot body, which sliding is caused by actuating the         handle, causes not only the first rail guide element but also         the locking element to be set into the non-pivoted and/or         retracted initial state, and     -   in step e), not only is the receiving element separated from the         first portion of the bracket element and the climbing boot         released from being guided by the climbing rail, but the         climbing boot is also released from being locked on the bracket         element.

If the climbing rail is mentioned, it always means a climbing rail with or without a climbing lift rail. This method has the same advantages and effects as in the method described above, wherein additionally the locking element for locking the climbing boot on the bracket element is included in the coupling of the sliding element in order to allow the release of the locking state of the climbing boot on the bracket element as a result of the actuation of the handle.

A further method according to the invention for decoupling the climbing boot coupled to the concreting segment of the building is carried out with the following steps if the climbing boot is arranged between the concreting segment and a climbing rail guided by the climbing boot:

-   -   step b2) is additionally carried out between steps b) and c):         B1) providing the climbing boot with at least one latching/snap         element arranged on the main boot body so as to be pivotable         and/or extendable, which latching/snap element interacts with a         holding element of the climbing rail and/or a climbing lift         rail, which is slidable relative to the climbing rail and is         guided by the climbing rail, for holding element the at least         one latching/snap element in such a way that, in the pivoted         and/or extended holding state, the climbing rail is suspended in         the climbing boot in the opposite direction to a climbing         direction,     -   in step c), the sliding element is designed in such a way that         it is mechanically coupled not only to the main boot body,         either to the first rail guide element or the first rail guide         element and the locking element, but also to the latching/snap         element, and, if not only the first rail guide element is in the         guidance state or the first rail guide element is in the         guidance state and the locking element is in the locking state,         but also the latching/snap element is in the pivoted and/or         extended holding state, sliding of the sliding element in         relation to the main boot body in the decoupling direction,         which sliding is caused by the actuation of the handle, results         in not only the first rail guide element or the first rail guide         element and the locking element, but also the latching/snap         element being set in each case into the non-pivoted and/or         retracted initial state in order to not only release the         climbing boot from being guided by the climbing rail or from         being guided by the climbing rail and locked on the bracket         element, but also to release it from the holding state of the         climbing rail and/or climbing lift rail,     -   in step d), the sliding of the sliding element in relation to         the main boot body, which sliding is caused by actuating the         handle, causes not only the first guide rail guide element or         the first rail guide element and the locking element, but also         the latching/snap element to be set into the non-pivoted and/or         retracted initial state, and     -   in step e) not only is the receiving element separated from the         first portion of the bracket element and the climbing boot         released from being guided by the climbing rail or the receiving         element separated from the first portion of the bracket element,         the climbing boot released from being guided by the climbing         rail and the climbing boot released from being locked on the         bracket element, but the climbing boot is also freed from the         holding state of the climbing rail and/or climbing lift rail.

If the climbing rail is mentioned, it always means a climbing rail with or without a climbing lift rail. This method has the same advantages and effects as in the method described above, wherein additionally the latching/snap element for holding the climbing rail/climbing lift rail is included in the coupling of the sliding element in order to allow the release of the climbing boot from the climbing rail/climbing lift rail as a result of the actuation of the handle.

A further method according to the invention is used to couple a climbing boot to be coupled to a concreting segment of a building, wherein

-   -   the sliding element is designed in such a way that, if the first         rail guide element, the first rail guide element and the locking         element, the first rail guide element and the latching/snap         element, or the first rail guide element, the locking element         and the latching/snap element are in each case in the         non-pivoted and/or retracted initial state, sliding of the         sliding element in relation to the main boot body in a coupling         direction opposite to the decoupling direction, which sliding is         caused by an actuation of the handle, results in the first rail         guide element being set into the guidance state, the first rail         guide element being set into the guidance state and the locking         element being set into the locking state, the first rail guide         element being set into the guidance state and the latching/snap         element being set into the holding state, or the first rail         guide element being set into the guidance state, the locking         element being set into the locking state and the latching/snap         element being set into the holding state in order to move the         climbing boot into the guide of the climbing rail, to move the         climbing boot into the guide of the climbing rail and lock it on         the bracket element, to move the climbing boot into the guide of         the climbing rail and set it into the holding state of the         climbing rail and/or climbing lift rail, or to move the climbing         boot into the guide of the climbing rail, lock it on the bracket         element and set it into the holding state of the climbing rail         and/or climbing lift rail. The sliding plate is therefore         designed in such a way that the climbing boot is not only         decoupled from the bracket element or the bracket element and         the climbing rail and/or climbing lift rail by actuating the         handle, but can also be coupled thereto again by actuating the         handle again. This ensures easy, error-free and safe coupling         and decoupling of the climbing boot.

When the method steps are carried out to decouple a climbing boot coupled to a concreting segment of a building in such a way that

-   -   the handle is arranged in an upper portion of the climbing boot         or is formed as an upper end of the climbing boot when the         climbing boot is oriented upward in a vertical climbing         direction,     -   the sliding element is mechanically coupled at least to the main         boot body in such a way that the actuation of the handle in the         decoupling direction is effected by means of a pulling movement,         in particular with one hand, in the climbing direction         vertically upwards and away from the main boot body, and     -   in the continuous pulling movement in the climbing direction,         the climbing boot is released from being guided by the climbing         rail and/or climbing lift rail, released from being guided by         the climbing rail and/or climbing lift rail and released from         being locked on the bracket element, released from being guided         by the climbing rail and/or climbing lift rail and freed from         the holding state of the climbing rail and/or climbing lift         rail, or released from being guided by the climbing rail and/or         climbing lift rail, released from being locked on the bracket         element and from the holding state of the climbing rail and/or         climbing lift rail and removed from the concreting segment by         the handle,         the climbing boot can be decoupled from the bracket element or         from the bracket element and the climbing rail/climbing lift         rail in one continuous pulling movement and removed from the         concreting segment using the handle directly thereafter, i.e.,         without setting it down. This is a simple and safe working step         for the construction worker on site, which can also be done with         one hand.

If, in addition, for coupling a climbing boot to be arranged on a concreting segment of a building, the climbing boot held on the handle is brought closer to the concreting segment above the bracket element and, in a continuous movement opposite to the climbing direction in the coupling direction opposite to the decoupling direction, the receiving element is applied to the first portion of the bracket element, and additionally the climbing boot is set into the pivoted and/or extended guidance state, set into the pivoted and/or extended guidance state and locked on the bracket element, set into the pivoted and/or extended guidance state and set into the holding state of the climbing rail and/or climbing lift rail, or set into the pivoted and/or extended guidance state, locked on the bracket element, and set into the holding state of the climbing rail and/or climbing lift rail, coupling the climbing boot to the bracket element or to the climbing lift rail is just as easy and safe as a decoupling the climbing boot from the climbing rail/climbing lift rail. When the climbing boot is coupled by a movement vertically downwards counter to the climbing direction, it does not have to be lifted against gravity, which simplifies the coupling step of the climbing boot, in particular when said coupling step is performed with one hand.

The method steps according to the invention for decoupling and/or coupling the climbing boot are preferably defined as a cycle and the cycle is run through until a frame and/or protective wall fastened to the climbing rail has reached a further or a plurality of further floors of the building or a next concreting segment of the building to be concreted.

DETAILED DESCRIPTION

FIG. 1 a is a side view of the climbing boot 1 according to the invention in a “closed” position, in which rail guide elements 3 a, 3 b (rail guide element 3 b is concealed by rail guide element 3 a and therefore not shown) are in a guidance state, i.e., in the “closed” position. The climbing boot 1 has a main boot body 2 having the first rail guide element 3 a, which is arranged on the main boot body 2 so as to be pivotable. In the pivoted guidance state in the “closed” position, a climbing rail introduced between the rail guide elements 3 a, 3 b is guided by the rail guide elements. The climbing boot 1 has a receiving element 5 that is comprised by the main boot body 2 and that has a recess 5 a, for example of cylindrical shape, in the X direction, which recess is open in the negative Z direction counter to a climbing direction in the Z direction, i.e., downwards, in order to receive a bracket support element of the bracket element as part of the bracket element when the climbing boot 1 is placed on the bracket element in the negative Z direction, i.e., from above. After application to or placement on a portion of the bracket element, as shown further below in FIGS. 1 a and 1 b , the receiving element 5 interacts with the portion of the bracket element to introduce a load of the climbing boot 1 into the bracket element. The climbing boot 1 also has a sliding element 6 that is provided with a handle 7, arranged slidably with respect to the main boot body 2 and guided by the main boot body 2, wherein the sliding element 6 is designed in such a way that it is mechanically coupled to the main boot body 2 and the first rail guide element 3 a, and, when the first rail guide element 3 a is in the guidance state, sliding of the sliding element 6 in relation to the main boot body 2 in a decoupling direction Z, which sliding is caused by an actuation of the handle 7, results in the first rail guide element 3 a being set into the non-pivoted initial state, i.e., the “open” position, in order to release the climbing boot 1 from being guided by the climbing rail.

FIG. 1 b is a side view of the climbing boot 1 according to the invention in a second embodiment in a “closed” position, in which the rail guide elements 3 a, 3 b (rail guide element 3 b is not shown) are in a guidance state, i.e., in the “closed” position, a locking element 4 in the locked state, and a latching/snap element in the form of a pawl (not shown in FIG. 1 a ) is in a holding state, i.e., in each case likewise in the “closed” position. The climbing boot 1 therefore has a locking element 4 that is arranged on the main boot body 2 so as to be pivotable and interacts with a portion of the bracket element of the concreting segment of the building to be erected in such a way that, in the pivoted locking state, i.e., in the “closed” position, the climbing boot 1 is detachably locked on the bracket element. In particular, the climbing boot 1 can have, for this purpose, the receiving element 5 that is comprised by the main boot body 2 and has the recess 5 a in the X direction, which recess is open in the negative Z direction counter to a climbing direction in the Z direction, i.e., downwards, in order to receive the bracket support element of the bracket element when the climbing boot 1 is placed on the bracket element in the negative Z direction, i.e., from above. In this case, the receiving element 5 interacts with the locking element 4 of the main boot body 2 to lock the climbing boot 1 on the bracket element when the locking element 4 is in the locked state. The climbing boot 1 also has the sliding element 6 provided with the handle 7, arranged so as to be slidable in relation to the main boot body 2, and guided by the main boot body 2, wherein the sliding element 6 is designed in such a way that it is mechanically coupled to the main boot body 2, the first rail guide element 3 a and the locking element 4, and, when the first rail guide element 3 a is in the guidance state and the locking element 4 is in the locked state, sliding of the sliding element 6 in relation to the main boot body 2 in a decoupling direction in the Z direction, which sliding is caused by an actuation of the handle 7, results in the first rail guide element 3 a and the locking element 4 being offset in each case into the non-pivoted initial state, i.e., the “open” position, in order to decouple the climbing boot 1 from the bracket element and to release it from being guided by the climbing rail.

All of the features described below for further embodiments of the climbing boot 1 according to the invention shown in FIG. 1 b et seq. also apply to the first embodiment of the climbing boot 1 according to the invention shown in FIG. 1 a , provided the features do not relate to the locking element 4 and the latching/snap element or are connected to these elements.

The climbing boot from FIG. 1 b is shown in a three-dimensional external view with the bracket element 8 a for fastening to a ceiling and the climbing rail 9 in the “closed” position in FIG. 2 a , wherein the climbing boot 1 in FIG. 2 b is shown in the “open” position and with the bracket element 8 b for fastening to a wall in a further embodiment. In FIG. 2 a , the bracket element 8 a is oriented in the Y direction and can be fastened to an already finished concreting segment (not shown), for example by means of screw connections. In both figures, the climbing boot 1 is shown in each case on a climbing rail 9 oriented in the climbing direction, i.e., Z direction. In FIG. 2 a , the climbing boot 1 is in the “closed” position in which the rail guide elements 3 a, 3 b guide the climbing rail 9 in that portions of the climbing rail 9, which are oriented in an X/Z plane, are surrounded by the rail guide elements 3 a, 3 b. Although it is sufficient for the invention if one of the two rail guide elements 3 a, 3 b, in particular the first rail guide element 3 a, is designed so as to be pivotable, in the case of the climbing boot 1 shown in FIG. 1 , both the first rail guide element 3 a and the second rail guide element 3 b are arranged on the main boot body 2 so as to be pivotable. In the “closed” position, the bracket element 8 a is also locked, i.e., detachably fastened, on the climbing boot 1, more precisely on the main boot body 2 of the climbing boot 1, by means of the locking element 4. The bracket element 8 a has a bracket support element 8 c in the form of a bolt that is oriented in the X direction and is guided into the opening 5 a of the climbing boot 1 in order to be fixed by the locking element 4 by means of the receiving element 5 and thus to connect the bracket element 8 a to the climbing boot 1. When the locking element 4 is in the locked state and the rail guide elements 3 a, 3 b are in the guidance state in which the climbing rail 9 is guided by the rail guide elements 3 a, 3 b, the sliding element 6 is inserted with the handle 7 counter to the decoupling direction in the Z direction in relation to the main boot body 2 in such a way that sliding of the sliding element 6 in the negative Z direction in relation to the main boot body 2 is not possible.

In contrast to this, in FIG. 2 b , the sliding element 6 is slid relative to the main boot body 2 by sliding in the Z direction, which sliding is caused by an actuation of the handle 7, in such a way that the rail guide elements 3 a, 3 b and the locking element 4 are in each case set into the non-pivoted initial state, i.e., in each case into the “open” position. When the handle 7 is fully actuated, the sliding element 6 cannot be slid any further in the Z direction in relation to the main boot body 2 in order to set the rail guide elements and the locking element in each case into the “open” position. When the rail guide elements 3 a, 3 b and the locking element 4 are in the “open” position, i.e., in their initial states, after the handle 7 has been actuated in the Z direction, the climbing rail 9 can be freed from being guided by the rail guide elements 3 a, 3 b and the bracket element 8 b can be decoupled/released from the climbing boot 1. Thus, according to FIG. 2 b , the bracket receiving element 8 c in the form of a bolt is not locked by the locking element 4 and the bracket element 8 b can therefore be decoupled from the climbing boot 1. The climbing rail 9 can also be oriented in the X or Y direction, for example when the climbing boot 1 is used for a rail-guided climbing system on a ceiling, for example for the construction of a tunnel. The rail guide elements 3 a, 3 b and the locking element 4 do not have to be arranged on the main boot body 2 so as to be pivotable because an extendable arrangement of these elements or parts of these elements on the main boot body 2 is also possible. The sliding element 6 is thus coupled to the main boot body 2, the rail guide elements 3 a and/or 3 b and the locking element 4 in such a way that, when the sliding element 6 is slid in the decoupling direction in the Z direction in relation to the main boot body 2, the rail guide elements 3 a, 3 b and the locking element 4 are in each case set into the initial state, i.e., into the “open” position, and the climbing boot is decoupled by means of the handle 7 from the bracket element 8 a, 8 b and the climbing rail 9 in the Z direction and away from its position between the bracket element 8 a, 8 b and the climbing rail 9. The decoupling and removal of the climbing boot 1 upwards can be carried out in one continuous movement in the Z direction, in particular with one hand, which is easy and ergonomic for the user on the construction site. On the other hand, the climbing boot 1 can be held by the handle 7 between the bracket element 8 a, 8 b and the climbing rail 9 in the negative Z direction is inserted and, by pushing down the handle 7 and thus the sliding element 6 in the negative Z direction in relation to the main boot body 2, can be coupled/fastened on both the bracket element 8 a, 8 b and the climbing rail 9 in a further continuous movement.

FIG. 2 c shows the climbing boot 1 in a three-dimensional external view without the bracket element 8 a, 8 b and the climbing rail 9, wherein the rail guide elements 3 a, 3 b are in a position between their initial state and the guidance state, the locking element 4 is in the locked state and a latching/snap element 10 in the form of a pawl is in the holding state, i.e., in the “closed” position. Although not required for the climbing boot 1 of the invention, in the second embodiment of the climbing boot 1 according to FIG. 1 b , the latching/snap element is connected to the main boot body 2 so as to be pivotable in order to interact with a holding element of the climbing rail 9 and/or a climbing lift rail (not shown), which is slidable relative to the climbing rail 9 and is guided by the climbing rail 9, for holding the latching/snap element 10 in such a way that, in the pivoted holding state, i.e., in the “closed” position, the climbing rail 9 and/or the climbing lift rail can be suspended in the climbing boot 1 in the opposite direction to the climbing direction, i.e., in the negative Z direction. The sliding element 6 is therefore designed in such a way that it is mechanically coupled not only to the main boot body 2, the rail guide elements 3 a, 3 b and the locking element 4, but also to the latching/snap element 10 in the form of a pawl, and, if not only the rail guide elements 3 a, 3 b are in the guidance state and the locking element 4 is in the locked state, but also the latching/snap element 10 is in the pivoted holding state, sliding of the sliding element 6 in relation to the main boot body 2 in the Z direction, which sliding is caused by the actuation of the handle 7, results in not only the rail guide elements 3 a, 3 b and the locking element 4, but also the latching/snap element being set in each case into the non-pivoted initial state, i.e., in the “open” position, in order not only to decouple/release the climbing boot 1 from the bracket element 8 a, 8 b and from being guided by the climbing rail 9, but also to decouple it from the climbing rail 9 and/or a climbing lift rail. The sliding between the sliding element 6 and the main boot body 2 is not complete in order to decouple the climbing boot 1 from the climbing rail 9. Instead, the handle 7 is pulled approximately one third of the possible full slide and the first and second rail guide elements, also known as claws, are slightly opened relative to their “closed” position. FIG. 2 c shows the latching/snap element 10 in its holding state, i.e., closed. The sliding element 6 is slid in relation to the main boot body 2 by a partial slide, in which the rail guide elements 3 a, 3 b are located between their initial state and the guidance state, i.e., are partially pivoted, and the locking element 4 is still in the “closed” position like the latching/snap element 10.

The climbing boot 1 has a longitudinal axis L in the Z direction, wherein the climbing boot 1 is constructed and designed in an axially symmetrical manner in the X direction or negative X direction with respect to the longitudinal axis L. The sliding element 6 has protrusions 6 a, 6 b in the X direction or in the negative X direction, which protrusions ensure that when the handle 7 is not actuated and the climbing boot 1 is therefore in the “closed” position, the rail guide elements 3 a, 3 b cannot be brought into the initial state, i.e., the “open” position. In addition, sliding pivot arms 3 a 2, 3 b 2 (not shown, see FIG. 2 j ), via which the sliding element 6 having the handle 7 is rotatably coupled to the rail guide elements 3 a, 3 b, ensure that the rail guide elements 3 a, 3 b cannot move into the “open” position. The protrusions 6 a, 6 b therefore serve as a guiding safeguard for the rail guide elements 3 a, 3 b. Between slot elements of the sliding element 6 having slots in a Y/Z plane, the climbing boot 1 has a finger sliding element 11 having a finger grip 12, which finger sliding element is designed in such a way that it is coupled to the main boot body 2, the sliding element 6, the rail guide elements 3 a, 3 b and the latching/snap element 10, and, when the handle 7 is not actuated, finger sliding of the finger sliding element 11 in relation to the main boot body 2 and the sliding element 6 in an unlocking direction substantially in the Z direction, which finger sliding is caused by an actuation of the finger grip 12, results in the rail guide elements 3 a, 3 b being locked in the initial state, i.e., in the “closed” position, and the latching/snap element 10 being offset into the non-pivoted initial state, i.e., in the “open” position, so that the climbing rail 9 or the climbing lift rail is guided only by the climbing boot 1. Because the latching/snap element 10 is in the holding state, the finger sliding element 11 is not actuated.

FIG. 2 d is an enlarged view of a part of FIG. 2 c . Slot elements 2 a are provided on the main boot body 2, which slot elements are offset symmetrically with respect to the longitudinal axis L in the X direction or negative X direction, in the Y direction with slots 2 b, wherein a central axle element 2 c in the form of a bolt is slidable in the Z direction and guided oriented in the X direction by the slot elements 2 a. The sliding element 6 has, symmetrically with respect to the longitudinal axis L in the X direction and in the negative X direction, sliding slot elements 6 c having sliding slots 6 d, wherein the central axle element 2 c is guided by the sliding slot elements 6 c. The sliding element 6 is slid in the Z direction relative to the main boot body 2 in such a way that a path is traveled in each of the sliding slots 6 d in a substantially negative Z direction as partial sliding of the sliding element 6 in relation to the main boot body 2 in order to partially set the rail guide elements 3 a, 3 b into the initial state, i.e., the “open” position. In contrast to a state of the climbing boot 1 in which the handle 7 is not actuated, the state of the climbing boot 1 according to the illustration in FIG. 2 d is that the sliding element 6 is slid in the Z direction by the path of the sliding slots 6 d, and due to the coupling of the sliding element 6 to the rail guide elements 3 a, 3 b, the rail guide elements 3 a, 3 b are partially offset from their holding state to the initial state by this partial sliding.

FIG. 2 e is a first cross-sectional view of the climbing boot 1 shown in FIG. 2 c . The cross section does not extend through the longitudinal axis L, but offset in the negative X direction relative to said longitudinal axis L. The sliding element 6 having the handle 7 is connected via the sliding slot elements 6 c and the central axle element 2 c to locking arms 6 e, 6 f, which are coupled to the central axle element 2 c at their upper end in the Z direction and are coupled to a sliding axle element 4 b at their lower end in the negative Z direction, which sliding axle element is coupled to the locking element 4 in such a way that, when the handle 7 is actuated in the Z direction, the locking arms 6 e, 6 f are likewise displaced in the decoupling direction and cause the locking element 4 to be set into its initial state, i.e., into the “open” position. The latching/snap element 10 is coupled to the main boot body 2 so as to be pivotable about a latching/snap axle element 10 a that is oriented in the X direction. The finger sliding element 11 having the finger grip 12 is coupled to the latching/snap element 10, wherein the finger sliding element 11 is coupled to the sliding element 6 via the central axle element 2 c and the sliding slot elements 6 c. This is shown more clearly in a second cross-sectional view of the climbing boot 1 shown in FIG. 2 c , wherein the cross section of this figure is shifted in the direction of the longitudinal axis L, i.e., in the X direction, compared to the cross section in FIG. 2 e . In addition to the rail guide element 3 a, the sliding element 6 having the handle 7 and the main boot body 2, the finger sliding element 11 having the finger grip 12 can be seen, which finger sliding element has a slot in its upper region in the Z direction in order to be guided by the central axle element 2 c, and comprises two axle arms 11 a, 11 b in its lower region in the negative Z direction, at the lower end of which a finger axle element 10 b is present in the latching/snap element 10, which finger axle element connects the axle arms 10 a, 10 b of the finger sliding element 11 to one another. The latching/snap element 10 further comprises a spring element arm 10 c, of which one spring element 10 d, which in the present embodiment of the climbing boot 1 is designed as a compression spring, wherein a support is provided by the locking element 4 for the spring element at a lower end of the spring element in the negative Z direction. Instead of the locking arms 6 e, 6 f, pipe screw contours, as described on pages 8 to 10, can also be used. A combination of the pipe screw contours instead of the locking arms 6 e, 6 f with the other elements described in connection with FIG. 2 e is possible.

In FIG. 2 g, the climbing boot 1 shown in FIG. 1 b is shown in a three-dimensional external view in the “open” position, wherein the rail guide elements 3 a, 3 b, the locking element 4 and the latching/snap element 10 are in the initial state, i.e., in the “open” position. The sliding element 6 is slid not only by the path in the sliding slots 6 d but also by a path in the Z direction that can be traveled in the slots 2 b of the slot elements 2 a of the main boot body 2. Further sliding of the sliding element 6 in relation to the main boot body 2 in the Z direction is therefore not possible.

In the three-dimensional cross-sectional view of the climbing boot 1 in FIG. 2 h , the central axle element 2 c is guided at the upper end of the axle arms 11 a, 11 b and at the lower end of the sliding slots 6 d in the sliding slot elements 6 c. In addition, due to the central axle element 2 c, the finger sliding element 11 is entrained by the sliding element 6 in the decoupling direction in the Z direction so that the latching/snap element 10 is set into its initial state, i.e., the “open” position, and the spring element 10 d is compressed by means of the spring element arm 10 c in order to exert pressure on the locking element 4 so that the locking element 4 can be set into the locking state. As a result of the sliding of the sliding element 6 in the decoupling direction in the Z direction, the latching/snap element 10 is thus rotated clockwise about the latching/snap axle element 10 a and the spring element arm 10 c is displaced in the negative Z direction so that the spring element 10 d can exert pressure on the locking element via the support surface of the locking element 4 in order to reach the “closed” position. However, this is prevented by virtue of the fact that the sliding of the sliding element 6 in relation to the main boot body 2 causes the locking arms 6 e, 6 f to be displaced in the Z direction by the central axle element 2 c so that the locking element 4 is pivoted into the “open” position by the sliding axle element 4 b.

FIG. 2 i shows a cross section of the climbing boot 1 in the state in which the sliding element 6 having the handle 7 is slid in the Z direction by sliding in relation to the main boot body 2, which sliding results in the rail guide elements 3 a, 3 b, the locking element 4 and the latching/snap element 10 being set in each case into the initial state, i.e., into the “open” position. Further sliding of the sliding element 6 in the Z direction, for example, by pulling the handle 7 in the Z direction does not result in further sliding of the sliding element 6 in relation to the main boot body 2. The sliding element 6 is coupled to the finger sliding element 11 via the central axle element 2 c in such a way that the locking element 4 is pivoted about a locking axle element 4 a by means of the axle arms 6 e, 6 f. The latching/snap element 10 is rotated clockwise around the latching/snap axle element 10 a to the “open” position, wherein the spring element 10 d guided in the spring element 10 c can exert pressure on the support surface of the locking element 4, which remains in its initial state, i.e., the “open” position, because it is guided via the axle arms 6 e, 6 f.

FIG. 2 j is a rear view of the climbing boot shown in FIG. 1 b in the “open” position. The rail guide elements 3 a, 3 b are rotatably guided by rail guide axle elements 3 a 1, 3 b 1 and are coupled to the main boot body 2 via said rail guide elements. The sliding element 6 having the handle 7 is rotatably coupled to the rail guide elements 3 a, 3 b via the sliding pivot arms 3 a 2, 3 b 2. In order to pivot the rail guide elements 3 a, 3 b out in the Y direction when the sliding element 6 is slid in relation to the main boot body 2 in the decoupling direction in the Z direction, the sliding pivot arm 3 a 2 is coupled at a lower end to the rail guide element 3 a via a lower sliding pivot arm axle element 3 a 3 and at its upper end to the sliding element 6 via an upper sliding pivot arm axle element 6 h. Due to the axially symmetrical design of the climbing boot 1 in relation to the longitudinal axis L, the sliding pivot arm 3 b 1 is coupled at its lower end in the negative Z direction to the rail guide element 3 b via the sliding pivot arm axle element 3 b 3 and at its upper end in the Z direction to the sliding element 6 via the upper sliding pivot arm axle element 6 g. The coupling points for the upper sliding pivot arm axle elements 6 h, 6 g are arranged in a lower portion of the sliding element 6 in the negative Z direction below the protrusions 6 a, 6 b. The sliding element 6 is coupled to the main boot body 2 via the rail guide elements 3 a, 3 b by means of the sliding pivot arms 3 a 2, 3 b 2 in such a way that, after the handle 7 is actuated in the Z direction, the sliding pivot arms 3 a 2, 3 b 2 are oriented substantially perpendicular in the Z direction such that further sliding of the sliding element 6 in relation to the main boot body 2 is not possible. Sliding VO of the sliding element 6 in relation to the main boot body 2 results in the rail guide elements 3 a, 3 b, the locking element 4 and the latching/snap element 10 in each case being in the initial state, i.e., in the “open” position. In this state, an upper edge of the handle 7 is spaced apart by the distance AO from a lower edge of a lower support of the main boot body 2 for receiving the rail guide elements 3 a, 3 b.

In FIG. 2 k , the climbing boot 1 from FIG. 1 b is shown in a rear view in the “closed” position. The protrusion 6 a prevents the rail guide element 3 a from pivoting out in the direction of the “open” position, and the protrusion 6 b prevents the rail guide element 3 b from pivoting out in the direction of the “open” position. Measured from an upper edge of a support of the rail guide elements 3 a, 3 b for receiving the rail guide axle elements 3 a 1, 3 b 1 to an upper edge of the protrusions 6 a, 6 b, sliding of the sliding element 6 in relation to the main boot body 2 is zero (see sliding in the “closed” position VG). The sliding pivot arms 3 a 2, 3 b 2 are oriented horizontally in the X direction and ensure via stops on the rail guide elements 3 a, 3 b that the sliding element 6 cannot be slid further in the negative Z direction in relation to the main boot body 2. A distance from a lower edge of a support of the main boot body 2 for receiving the rail guide axle elements 3 a 1, 3 b 2 to an upper edge of the handle 7 AG is smaller than the distance AO by the sliding VO (see FIG. 2 j ). Due to the inserted state of the sliding element 6 relative to the main boot body 2, the finger grip 12 of the finger sliding element 11 is visible in FIG. 2 k , as opposed to FIG. 2 j.

FIG. 3 a shows a three-dimensional external view of the climbing boot 1 shown in FIG. 1 b in the “closed” position with the finger grip 12 actuated substantially in the Z direction in an unlocking direction. The rail guide elements 3 a, 3 b are in the guidance state and the latching/snap element 10 in the form of a pawl is in the initial state. The sliding element 6 cannot be slid further in the negative Z direction in relation to the main boot body 2, wherein, due to the actuation of the finger grip 12, the finger sliding element 11 is coupled to the latching/snap element 10 in such a way that the latching/snap element is displaced to its initial state, i.e., the “open” position.

In FIG. 3 b , the climbing boot 1 is shown in the state with the handle 7 not actuated, i.e., in the “closed” position, in which the rail guide elements 3 a, 3 b are in the guidance state and the latching/snap element 10 is in the holding state. Because the finger grip 12 is not actuated, the rail guide elements 3 a, 3 b, the locking element 4 and the latching/snap element 10 are in the “closed” position.

In contrast to the “closed” position of the climbing boot 1, the “open” position of the climbing boot 1 shown in FIG. 3 c is such that the sliding element 6 having the handle 7 is slid in the Z direction in relation to the main boot body 6 in such a way that further sliding in the Z direction is no longer possible. Therefore, the rail guide elements 3 a, 3 b are spread and are in their initial state, the locking element 4 is in the “open” position in the initial state and the latching/snap element 10 is in the initial state because the finger grip 12, which is actuated in the unlocking direction in a substantially Z direction, is entrained by the sliding element 6 and displaced in the Z direction by means of the finger sliding element 11.

FIG. 4 a is a side view of the climbing boot 1 according to FIG. 1 b in the “closed” position with the finger grip 12 actuated and latched in the unlocking direction. The rail guide elements 3 a and 3 b (3 b concealed by 3 a and therefore not shown) are displaced in the negative Y direction into the holding state in order to guide the climbing rail 9. In addition, the locking element 4 is transferred to the locked state, in which, with the receiving element 5 of the main boot body 2, it forms the opening 5 a for receiving the bracket support element 8 c of the bracket element 8 a, 8 b as the portion thereof. The central axle element 2 c guides the sliding element 6 in an upper portion of the sliding slots 6 b. The axle arm 6 f, behind which the finger sliding element 11 having the finger grip 12 is arranged, can be seen through the slot 2 b of the main boot body 2.

The climbing boot 1 in the state with the handle 7 not actuated and the finger grip 12 latched is shown in a three-dimensional external view in FIG. 4 b . The finger sliding element 11 is latched to the central axle element 2 c in the actuated position in such a way that the latching/snap element 10 is in its initial state, while the rail guide elements 3 a, 3 b are in the guidance state.

The cross-sectional view of FIG. 4 c shows the finger sliding element 11 in the latched state on the central axle element 2 c. For the latching, the finger sliding element 11 has a latching element 11 c in the form of two latching lugs that are arranged at a distance from the longitudinal axis L at equal distances in the X direction or in the negative X direction with respect to the longitudinal axis L. A slot provided in the finger sliding element 11, via which slot the finger sliding element 11 is guided by the central axle element 2 c, has a bulge 11 d in the Y direction due to the latching element 11 c, in which bulge the central axle element 2 c can be received for latching the finger sliding element 11. In the locked state, due to the actuation of the finger grip 12, the finger sliding element 11 is displaced in the Z direction in such a way that the latching/snap element 10 is rotated counterclockwise so that the spring element 10 d exerts pressure on the support surface in an upper portion of the locking element 4 to hold the locking element 4 in the locked state, i.e., closed.

FIG. 5 a shows the climbing boot shown in FIG. 1 b in the state when the handle 7 is not actuated, i.e., in the “closed” position, with the finger grip 12 not actuated in the unlocking direction. The latching/snap element 10 is therefore in the holding state, wherein a pressure is still exerted on the locking element via the spring element 10 d via the upper bearing surface of the locking element 4. The state of the climbing boot 1 in the “closed” position with the finger grip 12 not actuated is shown in FIG. 5 b in a three-dimensional external view, enlarged from FIG. 5 a . The finger sliding element 11 is not engaged in the central axle element 2 c. The handle 7 is not actuated in the decoupling direction in the Z direction, and the latching/snap element 10 engages in a holding element of the climbing lift rail 9 b, which is guided by the climbing rail 9 and can be displaced relative thereto. It is also possible for the latching/snap element 10 to engage in a socket of the climbing rail 9.

In FIG. 6 a , the climbing boot 1 is shown in a third embodiment with three latching/snap elements 10, 10′, 10″ in the “closed” position coupled to the climbing rail 9 with first and second climbing rail outer elements 9 a 1, 9 a 2. In the state coupled to the bracket element 8 a, 8 b, the bracket element would adjoin the climbing boot 1 in the Y direction in such a way that the receiving elements 5 surround the bracket support element 8 c, which would be oriented in the X direction. The climbing rail outer elements 9 a 1, 9 a 2 are each C-shaped, wherein the climbing rail outer elements are oriented away from each other in the X direction and parallel to each other in the negative X direction. In each case, an upper leg of the first climbing rail outer element 9 a 1 and of the second climbing rail outer element 9 a 2 is surrounded by the rail guide elements 3 a, 3 b, which are each in the guidance state, i.e., in the “closed” position. The climbing rail outer elements 9 a 1, 9 a 2 are connected to each other at a distance from each other by struts oriented in the X direction and distributed along the climbing rail 9 in the negative Z direction, for example via screw connections, as shown in FIG. 6 a . Between the climbing rail outer elements, a climbing lift rail guide element 9 a 4 is attached to each of the climbing rail outer elements, for example by means of a further screw connection, in order to guide the climbing lift rail 9 b, which is guided by the climbing lift rail guide elements 9 a 4 and is arranged displaceably relative to the climbing rail 9. The first latching/snap element 10, which is arranged centrally on the longitudinal axis L, is designed to engage in at least one holding element of the climbing lift rail 9 b and thus couple the climbing rail 9 to the climbing boot 1. In the X direction and in the negative X direction, next to the holding elements of the climbing lift rail, support elements are fastened in the Y direction to each of the climbing rail outer elements 9 a 1, 9 a 2, for example by means of a further screw connection 9 a 3. In the plan view of FIG. 6 a , the latching/snap elements 10′, 10″ are each arranged in the Z direction above holding elements of the climbing lift rail 9 b and the support elements of the climbing rail outer elements 9 a 1, 9 a 2, while the latching/snap element 10 is arranged below the holding element of the climbing lift rail 9 b.

In FIG. 6 b , the climbing boot 1 shown in FIG. 6 a is shown in a three-dimensional external view. The rail guide elements 3 a, 3 b are in the guidance state, which means that the sliding element 6 having the handle 7 is arranged in relation to the main boot body 2 in such a way that further sliding of the sliding element 6 in the negative Z direction in relation to the main boot body 2 is not possible. The central latching/snap element 10 arranged on the longitudinal axis L is located between the further latching/snap elements 10′, 10″ arranged adjacent to said latching/snap element in the X direction and in the negative X direction. Because the latching/snap elements 10, 10′, 10″ are each in the holding state, i.e., in the “closed” position, the finger sliding element 11 provided with the finger grip 12, which finger sliding element is guided by the central axle element 2 c, is not actuated such that the finger sliding element 11 cannot be slid in the negative Z direction in relation to the main boot body 2.

FIG. 6 c is a cross-sectional view of the climbing boot 1 shown in FIG. 6 a . The latching/snap element 10 in the form of a pawl engages in a holding element of the climbing lift rail 9 b, wherein the holding element of the climbing lift rail 9 b partially covers the further latching/snap element 10″ which is in the holding state, i.e., in the “closed” position, in such a way that the support element 9 a 5 can rest on the latching/snap element 10′ in the lower portion thereof in the negative Z direction. The climbing lift rail guide element 9 a 4 is fastened to the second climbing rail outer element 9 a 2 by means of a bolt, for example via a screw or welded connection. Because the latching/snap elements 10, 10′, are each in the holding state, the finger sliding element 11 is not slid, i.e., not actuated, in the negative Z direction in relation to the main boot body 2, which also applies to the handle 7, the sliding element 6 of which, like the finger sliding element 11, is guided by the central axle element 2 c. Due to the non-actuated handle 7, the climbing boot 1 is in the “closed” position in such a way that the locking element 4, which interacts with the receiving element 5, is in the locked state, i.e., also in the “closed” position. It is also possible for the central latching/snap element 10 to interact with holding elements of the climbing lift rail 9 b and for the further latching/snap elements 10′, 10″ to interact with holding elements of a further climbing lift rail, which, like the climbing lift rail 9 b, is arranged within the climbing rail outer elements 9 a 1, 9 a 2 for fastening the climbing rail 9 to the climbing boot 1. In this case, the climbing rail outer elements 9 a 1, 9 a 2 would have no support elements 9 a 5 (not shown).

The climbing boot 1 coupled to the climbing rail 9 and/or climbing lift rail 9 b, as shown in FIG. 6 a , is shown in FIG. 6 d in a three-dimensional external view. The central latching/snap element 10 is in the holding state, but it is not resting on a holding element of the climbing lift rail 9 b. The further latching/snap elements 10′, 10″, in contrast, each rest on a support element 9 a 5 that is fastened to each of the climbing rail outer elements 9 a 1, 9 a 2.

FIG. 6 e shows the climbing boot 1 spaced at a distance of, for example, 10 cm from the climbing rail 9 with the climbing lift rail 9 b and the climbing rail outer elements 9 a 1, 9 a 2 to better identify the arrangement of the latching/snap elements 10, 10′, 10″ in relation to the climbing lift rail 9 b and the support elements 9 a 5. The rail guide elements 3 a, 3 b, the latching/snap elements 10, 10′, 10″ and the locking element 4 are in the “closed” position such that the sliding element 6 having the handle 7 cannot be slid further in the negative Z direction in relation to the main boot body 2.

FIG. 6 f is a cross-sectional view the climbing lift rail 9 b guided by the climbing lift rail guide elements 9 a 4, which climbing lift rail is suspended with one of its holding elements in the latching/snap element 10 and thus transfers a load of the climbing system via the climbing rail 9 to the climbing boot 1. Each of the latching/snap elements 10′, 10″ does not engage with a lower portion of the support elements 9 a 5, so that the load of the climbing system is transferred via the climbing lift rail 9 b into the climbing boot 1 and via the climbing boot 1 into the finished concreting segment of the building to be erected. In contrast to the state of the climbing boot 1 relative to the climbing rail 9 and the climbing lift rail 9 b according to FIG. 6 f , in FIG. 6 g , the load of the climbing system is transferred to the climbing boot 1 via the latching/snap elements 10′, 10″, wherein the central latching/snap element 10 does not engage in a holding element of the climbing lift rail 9 b. The support elements 9 a 5 are arranged opposite the climbing lift rail guide elements 9 a 4 in the Y direction, i.e., in the direction of the climbing lift rail 9 with respect to the climbing boot 1.

In a further embodiment of the climbing boot 1, as shown in FIG. 7 a , the central latching/snap element 10 and the further latching/snap elements 10′, 10″ are arranged in such a way in relation to the climbing rail 9 having the climbing rail outer elements 9 a 1, 9 a 2 and the climbing lift rail 9 b that the central latching/snap element 10 can engage in a holding element of the climbing lift rail 9 b and the further latching/snap elements 10′, 10″ can each engage in recesses as holding elements of the climbing rail outer elements 9 a 1, 9 a 2. Alternatively, protrusions that interact with the latching/snap elements 10, 10′, can also be present as holding elements on the climbing rail outer elements 9 a 1, 9 a 2 and/or the climbing lift rail 9 b. For example, blocks can be welded to the climbing rail outer elements 9 a 1, 9 a 2, which blocks can engage in the pawls 10′ and/or 10″. The arrangement of the latching/snap elements 10′, 10″ not arranged centrally with respect to the longitudinal axis L in relation to the climbing boot 1 is shown in FIG. 7 a in that the climbing boot 1 is located at a distance of, for example, 10 cm from the climbing rail 9.

FIG. 7 b shows the state of the climbing boot 1 in the “closed” position coupled to the climbing rail 9 with the climbing lift rail 9 b. The latching/snap elements 10′, 10″, which are not arranged centrally with respect to the longitudinal axis L, each engage in recesses of the climbing rail outer elements 9 a 1, 9 a 2 in such a way that, when the climbing rail 9 is coupled to the climbing boot 1, the portions of the latching/snap elements 10′, 10″ guided through the recesses are located on outer sides of the climbing rail outer elements 9 a 1, 9 a 2 facing away from each other. The region between the climbing rail outer elements 9 a 1, 9 a 2 is therefore reserved for the climbing lift rail guide elements 9 a 4, the climbing lift rail 9 b and the latching/snap element 10 arranged centrally on the longitudinal axis L.

In FIG. 7 c , the climbing boot 1 engages with the latching/snap elements 10′, 10″ that are not centrally arranged in the holding elements 9 a 6 in the form of the recesses such that the climbing rail 9 having the climbing lift rail 9 b is held by the latching/snap elements 10′, 10″ arranged adjacent to the centrally arranged latching/snap element 10. The central latching/snap element 10 does not engage with a holding element of the climbing lift rail 9 b located in the negative Z direction below the central latching/snap element 10, as is the case when the climbing lift rail 9 b is pulled back in the negative Z direction in relation to the climbing rail outer elements 9 a 1, 9 a 2.

In contrast to the arrangement of the climbing rail 9 in relation to the climbing boot 1 according to FIG. 7 c , FIG. 7 d is an external view of the climbing boot 1 coupled to the climbing rail 9, in which the latching/snap elements 10′, which are arranged non-centrally, do not engage in the recesses of the holding elements 9 a 6, but the climbing rail 9 is held by the climbing boot 1 via the climbing lift rail 9 b and the latching/snap element 10, which engages in a holding element of the climbing lift rail 9 b. The climbing lift rail 9 b thus transfers the load of the climbing system to the climbing boot 1 via the central latching/snap element 10, wherein the climbing rail outer elements 9 a 1, 9 a 2 are guided by the rail guide elements 3 a, 3 b and are slidable in relation to the climbing lift rail 9 b.

FIG. 7 e is an external view of the climbing boot 1 coupled to the climbing rail 9, wherein the latching/snap elements 10′, 10″, which are arranged non-centrally, engage in recesses of the climbing rail outer elements 9 a 1, 9 a 2, which serve as holding elements 9 a 6, in order to couple the climbing rail 9 to the climbing boot 1. The central latching/snap element 10 in the form of a pawl, which is concealed by the climbing lift rail 9 b, does not engage in a holding element of the climbing lift rail 9 b, so that the climbing lift rail 9 b can travel in the Z direction relative to the central latching/snap element 10, which is not in the holding position. The climbing lift rail 9 b can also travel in the negative Z direction in relation to the central latching/snap element 10 as long as the latching/snap element 10, which is in the “closed” position, does not engage in a holding element of the climbing lift rail 9 b. A travel path of the climbing lift rail 9 b in relation to the climbing boot 1 is therefore dependent on a distance of adjacent holding elements of the climbing lift rail 9 b from engagement in the central latching/snap element 10. In the embodiment shown, the distance between the holding elements of the climbing lift rail 9 b in the Z direction for the pawl 10 of the climbing boot 1 is substantially the same as the distance between the recesses 9 a 6 of the climbing rail 9 for the further pawls 10′, 10″. The travel path, also called the stroke, is greater than the distances between the recesses in the climbing rail 9 or the distances between the holding elements in the climbing lift rail 9 b. The overlap region is required for climbing.

In FIG. 7 f , the climbing boot 1 is shown in the “closed” position at a distance of, for example, 10 cm with respect to the climbing rail 9 with the climbing lift rail 9 b in a three-dimensional external view in the fourth embodiment of the climbing boot 1. Recesses in the climbing boot 1 when the climbing boot 1 is coupled to the climbing rail 9 on legs of the climbing rail outer elements 9 a 1, 9 a 2 facing the climbing boot 1 serve as holding elements 9 a 6, by means of which the climbing rail 9 can engage in the latching/snap elements 10′, 10″ that are not arranged centrally. The latching/snap element 10, which is arranged centrally with respect to the longitudinal axis L, is designed to engage in holding elements of the climbing lift rail 9 b, which is arranged centrally between the climbing rail outer elements 9 a 1, 9 a 2. The climbing boot 1 is in the state in which it is not possible for the sliding element 6 to slide in the negative Z direction in relation to the main boot body 2, i.e., the handle 7 is not actuated in the decoupling direction in the Z direction, so that the rail guide elements 3 a, 3 b are in the guidance state, the locking element 4 is in the locked state and each of the latching/snap elements 10, 10′, 10″ is in the holding state.

By actuating the handle 7 in the decoupling direction, for example in the Z direction, the climbing boot 1 can be set into the state in which the rail guide elements 3 a, 3 b, the locking element 4 and the latching/snap elements 10, 10′, 10″ are in their initial state, i.e., in the “open” position. This is possible because the sliding element 6 is arranged so as to be slidable in relation to the main boot body 2 and is mechanically coupled to the main boot body 2, the rail guide elements 3 a, 3 b, the locking element 4 and the latching/snap elements 10, 10′, and when the rail guide elements 3 a, 3 b are in the guidance state, the locking element 4 is in the locked state and the latching/snap elements 10, 10′, are in the pivoted holding state, the sliding VO (see FIG. 2 j ) of the sliding element 6 in relation to the main boot body 2, which sliding is caused by the actuation of the handle 7, results in the rail guide elements 3 a, 3 b, the locking element 4 and the latching/snap elements 10, 10′, 10″ being set in each case into the non-pivoted initial state, i.e., in the “open” position, in order to decouple the climbing boot 1 from the bracket element 8 a, 8 b (see FIG. 2 a, 2 b ) and from the climbing rail 9 with or without the climbing lift rail 9 b and release it from being guided by the climbing rail 9 and/or the climbing lift rail 9 b.

FIG. 8 a is a three-dimensional external view of the climbing boot according to the invention in the open position in a fifth embodiment, wherein the climbing boot has four pawls, wherein first 10 ¹ and second pawls 10 ² can engage in holding elements of the climbing lift rail and third 10′ and fourth pawls can engage in recesses of the climbing rail. The sliding element 6 is mechanically coupled to the first 3 a and second rail guide elements 3 b by means of pipe screw contours, also referred to as slides. In this embodiment, the handle 7 is connected via the sliding element 6 to rails 13 a, 13 b, which, as shown, can be arranged substantially parallel to each other and substantially symmetrical to the longitudinal axis L of the climbing boot. In the mounted state of the climbing boot, the rails 13 a, 13 b are slidable/movable only in and counter to the climbing direction corresponding to the longitudinal axis L of the climbing boot, for example vertically in relation to the main boot body 2. The rail 13 a, 13 b can be designed as part of the sliding element 6. When the handle 7 is moved in the climbing direction, the rail 13 a, 13 b moves in the climbing direction, for example upwards, and when the handle 7 is moved counter to the climbing direction, the rail 13 a, 13 b moves against the climbing direction, for example downwards.

Parallel to the rail 13 a, 13 b, a further rail portion 14 a, 14 b, the length of which is shorter than the length of the rail 13 a, 13 b in its longitudinal direction, is connected to the rail 13 a, 13 b at one end of the rail 13 a, 13 b in the climbing direction, for example as shown at an upper end of the rail 13 a, 13 b, and is thus connected to the handle 7 via the sliding element 6 in such a way that a free end of the rail portion 14 a, 14 b, in the case of a closed climbing boot according to FIG. 8 b , can engage both in a first recess 15 a, 15 b of the main boot body 2 and in a first recess 15 ¹ of the first 3 a and second rail guide elements 3 b in order to secure the position of the rail guide element 3 a, 3 b. The other, for example lower end of the rail 13 a, 13 b, which, like the free end of the rail portion 14 a, 14 b, can engage in a second recess 16 a, 16 b of the main boot body 2 and also in a second recess 16 ² (only visible in FIG. 8 a for the rail guide element 3 b because it is shown covered for the other rail guide element 3 a) of the first 3 a and second rail guide elements 3 b, can also serve to secure the position of the rail guide element 3 a, 3 b.

A rod-shaped element 19 a (shown covered in FIG. 8 a for the rail 13 b), for example a bolt, is in each case fixed to the rail 13 a, 13 b perpendicular to a longitudinal axis of the rail and moves with the rail 13 a, 13 b when the handle 7 is displaced in or counter to the climbing direction. The rod-shaped element 19 a can be guided by a rod-shaped guide element, for example a further rail or a cylinder or axle element arranged parallel to the rail (not shown). The first 3 a and second rail guide elements 3 b have a third curved recess 18 a, 18 b having a width that allows a free end and/or a portion of the rod-shaped element 19 a to engage in the recess 18 a, 18 b or guide the recess 18 a, 18 b, i.e., allows it run in the recess 18 a, 18 b. The curved recess has a helical or threaded profile in order to rotate the rail guide element 3 a, 3 b when the rod-shaped element 19 a running in the recess 18 a, 18 b is displaced in or counter to the climbing direction relative to the main boot body 2 by an actuation of the handle 7. If, when the climbing boot is closed, as shown in FIG. 8 b , the handle 7 for unlocking the climbing boot is actuated/pulled in the climbing direction, i.e., upwards as shown in FIG. 8 a compared to FIG. 8 b , the rail 13 a, 13 b moves with the rod-shaped element 19 a in the climbing direction, i.e., upwards, when the main boot body 2 is stationary. Because the rail 13 a, 13 b and the rod-shaped element 19 a can only be displaced in the climbing direction, i.e., upwards, the rod-shaped element 19 a guides the rail guide element 13 a, 13 b during the displacement of the rod-shaped element 19 a in such a way that, due to the curved recess 18 a, the rail guide element 13 a, 13 b also rotates to such an extent that a fictitious straight line of the recess 19 a is formed at the location of the rod-shaped element 13 a, 13 b over the displacement of the rod-shaped element 19 a in the climbing direction, along which the rod-shaped element 19 a can move.

The first 3 a and second rail guide elements 3 b each comprise an at least in part cylindrical hollow body 17 a, 17 b, into which the third curved recess 18 a is introduced, for example over a length of the displacement path of the handle 7 relative to the main boot body 2. The rail 13 a, 13 b can thus be guided in the at least in part cylindrical hollow body 17 a, 17 b in such a way that the rod-shaped element 19 a can engage in the recess 18 a along its displacement path in order to guide the first 3 a and second rail guide elements 3 b in such a way that they are rotated relative to the main boot body 2 during the displacement of the handle 7. If the first 3 a and second rail guide elements 3 b are to be rotated in relation to the main boot body 2 to close the climbing boot, the handle 7 is displaced in relation to the main boot body 2 counter to the climbing direction in the same way as when the climbing boot is opened, such that, because the rail 13 a, 13 b and the rod-shaped element 19 a can only be displaced counter to the climbing direction, i.e., downwards, the rod-shaped element 19 a guides the respective rail guide element 3 a, 3 b during the displacement of the rod-shaped element 19 a in such a way that the respective rail guide element 3 a, 3 b rotates with the curved recess 18 a in order to set the climbing boot into the “closed” position.

The finger grip 12 is designed to actuate first 10 ¹ and second pawls 10 ² of the first latching/snap element and third 10′ and fourth pawls 10″ of the second latching/snap element. It is however also possible for a first finger grip element and a second finger grip element to be present instead of the finger grip 12, wherein the first finger grip element is designed in such a way that the first pawl 10 ¹ and the second pawl 10 ² can be actuated by the first finger grip element and the third pawl 10′ and the fourth pawl 10″ can be actuated by the second finger grip element independently of the first and second pawls 10 ¹, 10 ². In this way, the climbing boot can be released/unlocked independently from the climbing rail or from the climbing lift rail.

First and second pawls 10 ¹, 10 ² of the first latching/snap elements are arranged substantially on a first axis substantially perpendicular to the longitudinal axis L of the climbing boot at a distance from the longitudinal axis L, in particular at substantially equal distances from the longitudinal axis L, and third and fourth pawls 10′, 10″ as further latching/snap elements are arranged at a distance therefrom counter to the climbing direction on a second axis substantially perpendicular to the longitudinal axis L at a distance from the longitudinal axis L, in particular at substantially equal distances from the longitudinal axis L. The first and second pawls 10 ¹, 10 ² of the first latching/snap-on element and the third and fourth pawls 10′, 10″ of the second and third further latching/snap elements can be actuated in pairs. In order to keep the design compact perpendicular to the longitudinal axis L, the two pawls 10 ¹, 10 ² of the first latching/snap element are arranged offset with respect to the third and fourth pawls 10″ of the further latching/snap elements counter to the climbing direction, i.e., vertically. The first and/or the further latching/snap element(s) can also have more than two pawls.

First distances from the longitudinal axis L of the first and second pawls 10 ¹, 10 ² differ from second distances of the third and fourth pawls 10′, 10″ from the longitudinal axis, wherein the first distances are selected to be smaller than the second intervals. The first and second pawls 10 ¹, 10 ² interact with the climbing lift rail and the third and fourth pawls 10′, 10″ interact with the climbing rail. A reverse embodiment in which the first and second pawls 10 ¹, 10 ² interact with the climbing rail and the third and fourth pawls 10′, 10″ interact with the climbing lift rail is also possible.

The features of the invention described with reference to the illustrated embodiment, such as the latching/snap elements 10′, 10″ of the third or fourth embodiment of the climbing boot 1, which are not located on the longitudinal axis L, can also be present in other embodiments of the invention, such as the first or second embodiment of the climbing boot 1, unless otherwise indicated or per se prohibited for technical reasons. In addition, the latching/snap elements 10, 10′, 10″ can be actuated independently of one another by the handle 7 and/or finger grip 12, even if only embodiments are shown and described in the figures for the third and fourth embodiments in which these elements can be actuated simultaneously by the handle 7 and/or finger grip 12.
